fo a/ZZ zii/'wm it may-concern:

Be it known that I, NIcKLAs FRANZEN,

acitizen of the United States, residing at` Walton, in the county of Allegheny and State of Pennsylvania, have invented undiscovered certain new and 4useful Improvementsin Method of and Machine for Making Wire- Glass, ofwhich improvements the following is a specification. p

My invention relates to improvements in method of and machines for forming wireglass; and theobject ofv my improvement is economy in production and superiority of product.

My improvement concerns particularly the formation of wire-glass from a single batch of molten glass introduced into the pass between a pair of forming-rolls.

According to my invention one of the two forming-rolls is pitted-that is, provided with pocket-like cavities or culs-de-sacover its entire surface, after the manner set forth in Letters Patent No. 823,112, granted me June 12, 1906.

The improved method consists in introducing the wire progressively through thebatch of molten glass as the latter is being spread by the forming-rolls and introducing it free from contact with any forming-surface until it passesA between the rolls, where it comes into contact With the roll which is pitted. The sheet of glass which is produced by the forming-rolls `will then contain the Wire embedded in its body, and its surface will bear protuberances of unchilled glass left by the pits in the pitted forming-roll. These excrescences or protuberances are reduced to produce a level and polished surface in any preferred mannensuch asl by receivingsaid sheet upon a table and compressing it 'beneath a roll.

In the accompanying drawings, which form part of this specification, I have shown in alternative form a machine embodying and in o eration performing my improvement. T ie two gures show, diagrammatically, in transverse vertical section my improved machine.

A pair of forming-rolls 1 and 2 are spaced and arranged to form between them a hopper-like receptacle for moltenr glass, and.

side by side in horizontal position and parallel one with another. They are rotatable in directions indicated by arrows a and b accordingly they are preferably arranged to spread to a sheet the batch of moltenl glasscarried between them.

Means are rovided for introducing the u Wire through t e receptacle for the glass and g into contact with the pitted forming-roll,

and such means preferably consist of a positioning-roll 3, arranged abovesaid formingrolls, over which the wire passes and from which it extends to contact with the pittedl roll, the point of contact being ypreferably in the pass between the rolls, as shown. This wire when introduced into the pass between the rolls, molten glass being teemed between them, will be firmly held, and may, if desired, be subjected to tension.

It will be understood that as the wire advances through the batch of molten glass and into contact with the pitted roll it becomes coated with molten glass, and at the point of contact a thin film of glass lies between the wire and the surface of the roll.

'lhe operation of the parts thus far described will readily be understood.l The wire A is carried over positioning-roll 3 and down into the pass between rols 1 and 2. Molten glass is then teemed into the receptacle, which rolls l and 2 form in a batch B. The molten glass passes freely through the wire, which is thus embedded in it. The glass also closes and partly fills the culs-desac in the surface of the pitted roll, entrap ping in each a small cuantity of air, which insulates the glass at these points from chilling contact with the roll-body. The rolls 1 and .2 are then rotated, and thewire being permitted to advance according] a sheet of wire-glass C is formed, which escends from between the rolls 1 and 2.` This sheet C contains the wire embedded in its body, andits surface bears excrescences of unchilled glass produced by the culs-de-sac inthe surface of this pitted roll.

It will be' observed of the machine arranged as shown in the drawings that the sheet C, passingfrom betreen the formingrolls 1 and 2, descends to rest `ipon the table, which is arranged to sustain 1,. Such an ar- ICO `1readdxr described are uncongealed andfsoft' and as the sheet @descends this unhardened' glass which forms these protuberances will sag downward by; gravity into contact ,With

and Will coalesce with lower protuberances. This saggine will tend to dragrnore r less glass through the meshes of the Wire and*to al greater or less extent to cause-the; EQtuber.-

ances to coalesce.
